SAND CUTTER.

Application :filed November 26, 192i). 'Serial No. 425,390.

To all whom 25 may kconce/m.'

Be it .known that we, Jenn E. CHAMBERS and Eninn'r L. VAN DoLsnN,citizens of the United States, residing at Shelbyville, in the county ofShelby and State of Indiana, have invented a new and usei'ulSand Cutter,ot which the following .is a specication.

It is the ,object ot our invention to pro-k tion, with some oi the partsbroken away or in section; Fig. 2is a plan of such machine; and Fig. 3is a tront elevation ot such machine.

A main tractor haine 10 provided at the rear with a step 11 on which theoperator may stand is supported lat the -rear by two traction wheels 12,and'at the front has a 'forwardly projecting ,pivot pin 13 Von which ispivotally mounted a `casting 14 which' in turn has pivotally mounted init on a horizontal transverse axis an inverted U-shaped trent frame 1:5on the downwardly extending arms of which are two caster wheels 1.6.Both the yfront and the rear wheels are separated sufficiently far apart'.to str/addice the new of Vsand 17. r-lfhe pivot lmounting 13 lpermitsthe Jiront trame 15 .to .tilt relatively to themain -frame 10 as mayberequired by .unevenness ofthe floor, while still permitting :all foursupporting wheels'to remain -on the ground. rEhe iront trame 15 ispreterab'ly vertically adjustable with respect to the caster wheels 16,by having collars 178 for the yupper ends `of Vthe caster wheel frames19 to bear against, which collars 18 are vertically adjustable along thearms lot the -frame 15 and clampable .thereto by setscrews 2O in anydesired position. The collars 418 are connected to the rear part oit themainframe 10fby links 21, pivoted to such main tra-me fand tosuch'collars on loose pivot pins 22 which permit relative movement inmore than one plane.

'Mounted on the trame 10 is a .suitable engine 25, or other source ,ofpower, the driving shaft 26 ot which maybe connected to or disconnectedfrom an alined Shah/H27 by a clutch 28, which is controlled by a tootpedal 29 connected to its movable member by .a Vlink 30 and bell-.crank31 or other suitable connection. A 'sleeve 32 is -splinedon the shaft 27and shiftable along it by .a push rod 33 in either direction fromthe'lneutral position shown to produce rapid torward driving by cansino'intermeshing oi a pinion 34 with a gear 35 on a countershaattt .orlessrapid rearward drivingby causing the interineshing of a pinion .37 withan idler 38 meshing with a gear 39 also iXed on the shaft 36 but smallerthan the gear 35. The shaft 3e has a worm-drive -connection k40 to adifferential'41, from which project laterally two differential shafits42'each provided with za small driving pulley yor sprocket 43 connectedby a belt er chain 44 to a larger pulley .or sprocket 45 on the`corresponding traction wheel 12. Each differential sha-ft has a brakevdrum 46, with which is associated abralre band 47 operable b-y a lever48 accessible to `the operator. manipu-v lating the brake lever 48 ofwhich .there is one for eaichside, the operator may steer the machine asdesired. 1 I

lined with the shaft27 is still another shaft 50, which is connectibleto, and disconnectible from the shaft 27 `by a jaw clutch 51 operable bya pull rod .52, also accessible yto the operator. `The shaft 5() is,connectedV by worin gearing 5.3 .to a transverse sha-it ,54, onopposite ends ot which are two cranks 5,5 provided with counterweights56. The cranks ,55 are pivotally connected to ther upper ends of tworods 57, which Vcorrespond to shovel `handles and which at their lower.ends are iattached to one `or more shovel blades 58, which if more thanone move vas one. Links .59 con-V nect intermediate points of the Arods57 with the main frame 10. As axresult, when the transverse cranlz 54'lis in operation, the lower edge ot theblade or blades 58 describes a.path such as indicated bythe chain line 60, the ripper part v.of lwhichis above the top of the sand Arow 17; so that when-'the blade 58 isstationary at the yupper part of its path the machine maybe movedvtorward or rearward without interference between ine, sand row and theblade, and when the blade 58 isin motion and the .ima-

chine is moving rearward the blade cuts into the sand row 17 and scoopsup the sand and throws it directly forward, or in the opposite directionto the movement of the machine, the movement of the blade or blades Sbeing in the plane of the machine move` ment.

In order that the shoveled sand mayY be broken up even more than by theshoveling action, and that the shoveled sand may be piled in a Smoothridged row instead of being scattered, the front frame l5 carries animperforate slanting hopper-shield 61, which is conveniently made ofsheet met l and in cross-section (Fig. 2) is in the form of a flattenedV with its apex forward. This hopper-shield is slanted so that its upperend is farther forward than its lower end. The sand thrown by the shovel58 strikes the hopper-shield 60, andis broken up by such striking; andthis sand is prevented from being scattered by the hopper-shield, andwhen it strikes the hopper-shield slides downward therein and drops fromthe lower edge thereof. Because of the "if shapeV and of the slant ofthis hopper-shield, the sand not only slides downward but also slidestoward the center of the shield, so that when it drops from the shieldas the machine travels backward during the cutting operation the sandforms a smooth ridged row. Preferably the hopper-shield is provided atthe bottom with a central inverted rl-shaped notch 62, the sides ofwhich preferably correspond to the natural slope of the sand. thuspermitting` the hopper-shield to entend downward on the sides of thesand row 17.

When it is desired to cut or temper a row of sand, the machine is fedforward astride such row, with the shovel 58 stopped in the upper partof its path so that it clears the top of the sand row. This is obtainedby a proper manipulation of the push rods 33 and 52 and of the footpedal 29. This forward movement may be relatively rapid, as no cuttingof the sand is being done. Whenthe front end of the row has beenreached, the direction of travel of the machine is reversed, by propermanipulation of the push rod 33 and foot pedal 29, to produce a slowrearward movement, and the shovel 58 is set into motion by throwing inthe clutch 5l by the push rod 52. As the machine travels rearward, theshovel 58, traveling` in its rearwardly-shifting path 60, cuts into theuncut sand 67 and throws successive shovel-fuis of such sand against thehopper-screen 6l, which drops it in a smooth ridged row 17 of out sand.lThe breaking up of the sand is obtained both by the shoveling Aactionand by the striking of the sand against the hopper-screen.
